I am a Christian, of the Reformed variety. More particularly, I am a member of the Lansdale Presbyterian Church which is a member of the "Presbyterian Church in America" denomination.
Dispensationalism, which is taught by Upper Bucks Christian School in an implied fashion (which I consider sneaky), attempts to divide the Bible into separate sections, each in which God presents man with a means of salvation "if he only does ---".
It should be noted that many who follow this view do not even know that it has a name, or that any other literal method to interpret the Bible exists. They also do not realize that Dispensationalism is NEW, and was never held to by any of the great Reformers.
While proponents may sincerely believe such a view is accurate ("Fundamental"), I challenge them to consider the view's implications, and to read what those who formulated the view have written, and THEN ask themselves, is this view really "Fundamental", or is it an errant knock-off of the true Gospel?
Here is a good refutation of Dispensationalism with scripture quotations.
Such a philosophy implies works-based salvation if taken consistently, even though proponents of the position deny it.
In contrast, I believe the 5 points of Calvinism. (TULIP)
(T)otal Depravity (all men are sinners)
(U)nconditional election (God chooses not based on works)
(L)imited atonement (Jesus dies only for the elect)
(I)rrisistable grace (God's chosen cannot resist His call)
(P)erserverence of the saints (you cannot lose your salvation)
Here is a concise
explanation of Calvinism with scripture references.
Remember, it is by GRACE through FAITH, not the other way around.
God's action is first, salvation is not based on works. Nothing is by chance;
everything is according to God's eternal, infallible plan. (Ephesians 2:8,
Ephesians 1:11)
